Welcome to DV, liquid tension. As Barbizzle said, check out the Tutorials and see if one of the methods there might help you out. The biggest thing, I've found is learning how to tell the difference between being awake and being asleep (obviously). Reality checks are helpful in that area, and if you can remember to do those wholeheartedly, that could help you out as well.

Let us know if you need anything else
